While unethical actions may arise from conscious, deliberate and reflective choices to do ‘wrong,’ many unethical decisions emerge instead from an absence of awareness of ethical responsibility. The metaphor of ‘blind spots’ has been deployed productively to describe mental obstacles that impede ethical responsibility at the individual level, but do not rise to the level of conscious awareness. Blind spots prevent us from attending to relevant data, different points of view, alternative solutions, and foreseeable consequences crucial to forging an ethical response. We identify three common myths that tend to foster ethical blind spots at the individual level by rendering the limited and vulnerable character of our ethical awareness unavailable to conscious consideration: the myth of moral self-image, the myth of self-sufficiency, and the myth of the bystander. Finally, we highlight practices that incorporate dissent and critical inquiry into organizational norms. Such practices, we argue, offer an important way of challenging the myths that support ethical blind spots.
